Visit DevinBottom line
ChatGPT is the clear winner: 8.8/10 (A-tier) versus 7.4/10 (B-tier). Devin isn't a bad tool, but on every category that drives the overall score, ChatGPT comes out ahead. The tier gap is repeatable -- not methodology noise -- and the day-to-day experience reflects it.
On pricing, ChatGPT starts free while Devin requires a paid plan from day one ($20+). If you're testing the waters or running an occasional workload, that gap matters more than the score differential. ChatGPT starts at $0; Devin starts at $20. Compare what each entry tier actually unlocks before you compare list prices -- the limits matter more than the headline number.
By use case: pick ChatGPT when everyone. Pick Devin when development teams that want to offload well-scoped tasks like bug fixes, test writing, and boilerplate code to an autonomous agent. The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap. If you're squarely in ChatGPT's lane, the tier-list ranking and the use-case fit point the same direction; if you're in Devin's lane, the score gap matters less than the fit.
Bottom line: ChatGPT is the better tool for most people right now. Pick Devin only when development teams that want to offload well-scoped tasks like bug fixes, test writing, and boilerplate code to an autonomous agent -- that's its lane, and inside that lane it still earns its place.
